Made the biggest road trip I've ever done last week. Put about 3600 miles on the car in the last week and a half or so. Down to visit the In-laws in South Carolina.

A couple interesting things. I've had the OBX header set on it for about 1.5 years. I didn't love that it has a flex section on each side where there wasn't one in the factory setup. But it seemed to work OK. Well, I think it bit me. Either the flex pipe tore, which allowed even more movement and caused the rear pipe to break, or the rear pipe was going to break anyway, and that extra flexibility tore the flex section. Either way, I had compounding exhaust leaks.
It's interesting, when the headers were new, they had a nice tight mesh flex section:

But after a couple winters, the mesh has swollen and deformed. I'm not surprised it failed.

I'm planning to cut out the flex, and having a solid piece of stainless welded in. At least on one side, that would return the rigidity to the system, and still allow the flexibility to ease install.
Still haven't decided what to do about the rear pipe. It's all a bit questionable. Probably not worth welding to the old pipe. I'll probably get an aftermarket replacement section, but then I start looking at the flange for the muffler.....ugh. I also don't like the sound of the car since the headers, so it might be a good opportunity to change it up completely.
I had the P0171 come back again (
I'll update that thread with more info), and managed to save the freeze frame data associated with it. Interestingly, it happened at idle.
Oh yea, and they're forecasting 8-12" of snow this weekend. Maybe I need to get the Hakkas back out of storage.
